Dominic is driving on a long road trip. He currently has 10 gallons of gas in his car. Each hour that he drives, his car uses up
Nostrana [21]

Answer:

(a) Equation: T_n = 11.25 - 1.25n

(b) 7.5 gallons

Step-by-step explanation:

Given

Current Gas = 10 gallon

Every Hour = -1.25 gallon

Solving for (a): An equation for the scenario

This question represents an Arithmetic Progression and will be solved using the following formula:

T_n = a + (n - 1)d

Where

a = 10

d = -1.25

Substitute these values in the formula

T_n = 10 + (n - 1) * -1.25

T_n = 10 -1.25n +1.25

Collect Like Terms

T_n = 10 + 1.25 - 1.25n

T_n = 11.25 - 1.25n

Solving for (b): In this case, n - 3

Substitute 3 for n in T_n = 11.25 - 1.25n

T_3 = 11.25 - 1.25 * 3

T_3 = 11.25 - 3.75

T_3 = 7.5

<em>7.5 gallon of gas left</em>

Find the length of the third side of each triangle mark
Sedaia [141]

Answer:

I'm going to use the Pythagoras theorem

1. hypotenus²= base²+height²

h²=80²+18²

h²=6400+324

√h²=√6724

hypotenuse= 82

2. 53²=45²+h²

2809=2025+h²

2809-2025=h²

784=h²

√784=√h²

h=28

3. 40²=b²+24²

1600=b²+576

1600-576=b²

√1024=√b²

b= 32

A triangle has side lengths of 36 in, 27in, and 61 in. Classify it as acute, obtuse, or right.
Lady_Fox [76]
<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:1) Square all 3 sides.36, 27, 61 </span><span> <span> <span> 1,296, </span></span></span> <span> <span> <span> 729, </span></span></span> <span> <span> <span> 3,721 </span> </span> </span> <span><span> </span> </span> <span><span> </span> </span> <span><span>2) Sum the squares of the 2 shortest sides.1,296 + 729 = 2,025

3) Compare this sum to the square of the 3rd side.2,025 < 3,721
if sum > 3rd side²   Acute Triangleif sum = 3rd side²   Right Triangleif sum < 3rd side²   Obtuse TriangleTherefore, it is an Obtuse TriangleSource:http://www.1728.org/triantest.htm

The amounts of household waste generated in a region during two years were 23,400,000 tons and 48,100,000 tons. What was the tot
trasher [3.6K]

The first step to do is to calculate first the total household waste generate for the two years. That is:

total waste generated = 23,400,000 tons + 48,100,000 tons

total waste generated = 71,500,000 tons

 

Now, to write either a very big number or a very small number in a form of scientific notation simply means to write it in a decimal form such as: 12.5 * 10^10

 

Now to write 71,500,000 in scientific notation, the decimal form is 7.15, however we still need to find out the * 10^n factor. The value of n depends on the number of places the decimal point was moved. If the movement was from right to left, the value of n is positive and if the movement was from right to left, the value of n is negative. Since the decimal point was moved by 7 places, hence the complete scientific notation is:

 

7.15 * 10^7 tons
